11.
NOTE:
A CP removed alarm will occur when the
OLIU
is removed.
An inc. OC3 LOS (blinking
FAULT
LED on
OLIU
) alarm
will occur at the other node connected to the removed fibers.
Other nodes will receive inc. VT AIS and inc.
STS AIS alarms.
At the starting OC-3 Node (Node 1), remove optical fibers and lift
the faceplate latch of
MAIN-2 OLIU
, then remove
MAIN-2 OLIU
.
12.
NOTE:
When the
29-Type OLIU
is installed in this step, an
unexpected CP type status and inc. OC12 LOS alarm
will occur. At the connecting node, an inc. OC3 LOS alarm
will occur. When fibers are reconnected, the
unexpected CP type status is still present at this Node
and an inc. OC12 LOF alarm will occur. An
inc. OC3 LOF alarm will occur at the connecting Node.
At the starting OC-3 Node (Node 1), install a
29-Type OLIU
into
MAIN-2 OLIU
slot and reconnect optical fibers.
13.
NOTE:
A OLIU connector failed alarm will occur when the
faceplate connector is removed.
At the other end of the OC-12 optical span being established,
remove the faceplate connector connecting
MAIN-1
and
MAIN-2
OLIU
s.
14.
NOTE:
A CP removed alarm will occur in this step when the
MAIN-1 OLIU
is removed. A inc. OC12 LOS alarm will
occur at the connecting Node with the
29-Type OLIU
installed.
At the other end of the OC-12 optical span being established,
remove optical fibers and lift the faceplate latch of
MAIN-1 OLIU
,
then remove
MAIN-1 OLIU
.
